I was in a similar situation just a few days ago and can attest to much of what has been said so far.
Got a really rough Model 65 and thoroughly polished it. Since I used fine steel wool, I imagined some of it might have gone inside the mechanism, so I needed to remove the sideplate off.
I'm mechanically inclined, and honestly have a way with restoring things. I watched the videos, used the correct screwdrivers, tapped it off and there it was... not a single piece of steel wool inside.
"OK, might as well just clean it since I'm at it"
Cleaned it... tried to cock the hammer... JAMMED.
My heart stopped for a second.
I looked everything and it all seemed right... I didn't understand.
I started panicking.
"OK.. let's see what it can be... I'll go ahead and disassemble it"
Did that and POOF, I managed to disengage a tiny spring that goes inside the trigger hand.
Result... the trigger hand wouldn't rotate the cylinder.
I couldn't for the life of me get it back in place and knew I had to take it to an armorer. At that point I felt like I wanted to crawl into a hole and die.
The armorer fixed it in 5 minutes, assembled it perfectly, did not charge me anything and let me go not without giving me the "please don't this again, kiddo"
1) If you've never done something before, it's quite likely you will screw up in some other way.
2) Before doing anything of the like, always have a back-up plan. IE: How are you going to fix it if something goes wrong?
3) By taking things apart, you do learn a lot. By screwing up, you learn even more.
4) Me, I learned that all it was necessary to unjam the action was to push the trigger and mechanism flush inside. If it's ever so slightly misaligned, the revolver jams. I also learned all the different parts and how it works internally.
5) Would I do it again? Yes, most likely. Depends on the situation. Would I have done it if it was my only revolver? Maybe not.
The choice is up to you, sir. There's nothing mysterious in there, it's great to take things apart. Just know that you can screw up and have a plan in case you do.
